May 31, 2024 · Value iteration is a fundamental algorithm in the field of reinforcement learning and dynamic programming. It is used to compute the optimal policy and value function for a Markov Decision Process (MDP). This article explores the value iteration algorithm, its key concepts, and its applications.

Oct 27, 2021 · The value iteration algorithm solves discounted infinite horizon MDP problems by leveraging results of Bellman operators, namely the optimal Bellman equation, contractions, and fixed points.

We will be covering 3 Dynamic Programming algorithms Each of the 3 algorithms is founded on the Bellman Equations Each is an iterative algorithm converging to the true Value Function Each algorithm is based on the concept of Fixed-Point

Construct a policy from a value function. Discuss the strengths and weaknesses of value iteration. Value Iteration is a dynamic-programming method for finding the optimal value function V ∗ by solving the Bellman equations iteratively.

The Value Iteration Algorithm can be seen as a version of Policy Iteration in which the policy evaluation step (generally iterative) is stopped after a single step.

Approximate the value function Using a function approximator ^v(s; w) Apply dynamic programming to ^v( ; w) e.g. Fitted Value Iteration repeats at each iteration k,

Sep 21, 2023 · Essentially, approximate value iteration offers a way to make classical value iteration asynchronous (only one state-action pair is updated at a time), while preserving its convergence guarantee.

Theorems in the literature on dynamic programming guarantee the convergence of value function iteration – under specified conditions on u,f,a – from any initial condition.

Value Function Iteration Well known, basic algorithm of dynamic programming. We have tight convergence properties and bounds on errors. Well suited for parallelization. It will always (perhaps quite slowly) work.
